I am in the very end of BL2 and obtaining its achievements. Spent some time in it grinding for the 2 achievements I got today.
In the Hammerlock's Hunt DLC I had to run around and kill few specific animals that only spawn in some specific areas on random intervals and not so commonly. Well, Google is our friend and I found instructions, what areas to check, and then do the classical "load your save game, run around, kill animals, save, quite and repeat".
The "
Challenge Accepted" achievement was even more bizarre. For it to be unlocked, you have to have "
Completed level 1 of all non-level-specific challenges with a single character". The problem is that 2 of the level 1 challenges become only available after you get level 5 in two other challenges. I was stuck of getting 750 point blank kills with shotguns, as it just is not my gaming style. I am more sneaky sniper kind of guy who uses turrets or grenades or rocket launcher to get rid of enemies form distance.

Then I played a little of Jetpack Joyride, but got no achievements there. Last but not least, did my "daily" moves in Win 8 AlphaJax and got one easy (just time consuming) achievement there.
